Cyclicity and rhythmicity are important features of sedimentary architectures. However, most geostatistical facies simulations techniques do not directly quantify or model them. A new approach based on Pluri-Gaussian Simulations, addresses this limitation of standard geostatistical techniques. It allows the modelling of cyclicity thanks to the introduction of a shift between Gaussian functions, and hole-effect variograms in the vertical direction. The results obtained in the three-dimensional simulation of a carbonate platform confirm that cyclicity and rhythmicity are properly modelled and that the method can be generalized to the modelling of both clastic and carbonate facies architectures.
